Meet Kualus, the Toa Hagah of Ice. Kualus is a member of an elite team of Toa who used to work for the Brotherhood of Makuta. A long time ago, Kualus and his fellow Toa Hagah were transformed into hideous half-beasts by the wicked Vortixx Roodaka. More recently, allied with the Toa Nuva, they found Roodaka and "persuaded" her to turn them back. They have since left on a mysterious mission into the heart of Metru Nui.
Kualus wears the Great Mask of Rahi Control, carved to resemble a Great Matatu. Originally it did not have the lens, but he added the unit himself; it enables him to see in infrared. He also decided to change its color to white, as an homage to a former Toa of Ice. He is armed with a subzero spear and the classic Hagah shield. Spinner power currently unknown.
Kualus's mask power has helped him develop a strong bond with the Rahi beasts that inhabit the world, especially the fliers. Fluent in the birds' languages, and a loner by nature, he usually prefers their company over that of other sentient beings. Out of all the team, Kualus was perhaps the least affected by his transformation into a Rahaga, since it drew him that much closer to his Rahi friends.
Kualus was actually the one who inspired Nuju to learn Rahi-speak, for which nobody is particularly grateful; since now Nuju will not communicate in any other language.
Here is a side view of Kualus. Notice the subtle effect of the Rahkshi teeth-things matching the vents in the top of his breastplate. I think it was a perfect choice.
A slightly older picture, in which you can see all of him at once.
Another slightly old shot.
This is a group shot from just after I finished my first version of Kualus. See the picture below.
An old shot, showing the original version of Kualus. Somehow those shoulders just weren't working for me, so I changed them. It didn't take much redesign, but it helped a lot.
This is sort of how I imagined Kualas. Here is somethings I would change. The mask has got to go. You should enlist the help of Heir of the Chronicler on bzpower to customize a mask. For example turning a different Kanohi white or silver, or removing the Eyepiece of the Matatu and have him make it symetrical. Give him Kopaka Mata's Ice sword for the end of his Sub zero spear.Use Thoks legs instead of Nuju's and Toa Inika Matoro's silver feet. Finally try using Kohrak Kals Sonic shield or Pahrak Kals Plasma shield as armor.just to make him look a little different compared to the other Toa Metru, and Hagah
Also Kualas has the Great mask of Rahi Control
